Research: revegetation approaches

In highly fragmented landscapes, natural recolonization isn’t sufficient for restoring native plant communities. Obtaining sufficient quantities of native seed is a major barrier to many reestorations,  especially large-scale projects Wild seed harvest is relied on to overcome commercial seed supply constraints but it introduces risks to the remnant vegetation being harvested. In a field survey of harvested and unharvested tallgrass prairies, Justin Meissen (2015) showed that short-lived, non-clonal species appeared to be most susceptible to decline from seed harvest. His dissertation research followed up on this finding with modeling and field experiments (forthcoming publications. We are continuing his field experiments to look at long-term effects of harvest
